Exhaust for 03 silverado

[sc_customs]

50 series is definitely quiter. I actually had a 50 series suv performance on my 4.8 before i went with the 40 series. I didn't like the 50 series...too quiet for me.

Here's a couple sound clips/videos of my set up, I realize that it won't sound exactly the same being that mine is a 6.0 but it will give you an idea. Basically I started with a true dual exhaust, cats back w/ no muffler. That lasted for about 2days, the noise was not good really didn't care for the sound one bit. I picked up a 50series big block 2inlet/2oulet Flowmaster and slapped that on and I just love the sound. Also I gained 2-3mpg and a little more throttle response. Now I know some of you guys love loud exhaust but I just wanted a little rumble to remind people that this is a truck and this definitly does that.

This is the video of starting it up..idling for a bit..and a couple good revs (Yea I know the exhaust is a little dirty, been raining here for days

Video 2
This is the cab noise with just about full throttle and then the cab noise cruising at 70mph..notice how the exhaust basically disappears once the cruise locks in.

I had a Gibson dual rear exit system on my 02 with a 4.8 and it sounded great imo. When you had it in 3 on the gear selector and let off at about 45mph it would give out a great rumble sound. The noise in the cab was great, low rumble at idle and great tone at cruising speed.

I use a Gibson 3" straight through muffler with an aftermarket 3" aluminized stock configuration pipe and 4" into 5" diesel single tip. With 383 cubic inches and Edelbrock headers (and cat) it sets off all the car alarms, but isn't annoying in the cab.
